Batteries can be linked together to allow for communication between packs. This communication is established using the RS485B and RS485C ports. Both ports are identical, so patch cables can be plugged into either port.
When linking batteries together, the DIP switches must be set to unique identities.
The following table depicts the DIP switch settings for all packs communicating together. Battery #1 must be the master that communicates with your Inverter or PC, and the rest of the batteries must use a unique address. No 2 inter-connected batteries may share the same address.
DIP switches in the “UP” position are “ON”. Additionally, the switches are numbered left to right, #1 – 4.
